Is it true Elastic deformation occurs when a material deforms as stress is applied?
Up to a point, it is possible to elastically deform any material. If the force is released, the material relaxes back to its original shape.
If a material is deformed too much, the deformation becomes permanent (plastic deformation) or fracture will occur in a non-ductile material such as glass.

Why doesn't a clay ball bounce?
Because it is too dense to bounce.No; clay isn't extraordinarily dense, and many other, more dense, materials do bounce. Clay doesn't bounce because it has no elasticity. When it hits a surface, it deforms (as do all materials), but it doesn't bounce back. It stays deformed. Clay is a plastic material. That doesn't mean "derived from oil" but it means that it doesn't recover from deformation; it stays deformed. That's why clay is such a good medium for sculpture. It's easy to mold.
What is residual strain?
Residual Strain is the same thing as permanent strain, as in permanent strain in a beam. If you refer to a stress vs strain plot, you'll see that this relationship in metals is linear up until the yield point where the metal plastically deforms. After stress slightly decreases due to this yielding, It will continue to increase, along with strain but on a more curve-shaped line. When stress is removed from the metal, it will slowly decrease back down to 0, but there will be an offset in the strain. The distance from where strain equals zero to this new point along the axis is the the residual strain left in the metal due to plastic deformation.
When is the kinetic energy transferred from object to object?
kinetic Energy. Energy is transferred from one object to another when a reaction takes place. Energy comes in many forms and can be transferred from one object to another as heat, light, or motion, to name a few. For the blue ball to move to the position of the green ball, energy must be given to the blue ball.
What does fluid mean?
A fluid is any liquid or gas that cannot sustain a shearing force when at rest and that undergoes a continuous change in shape when subjected to such a stress. Compressed fluids exert an outward pressure that is perpendicular to the walls of their containers. A perfect fluid lacks viscosity, but real fluids do not.
Elastic deformation occurs when a material deforms as stress is applied?
Yes, elastic deformation is reversible and occurs when a material is subjected to a stress but returns to its original shape once the stress is removed. This is due to the material's ability to store and release energy elastically as the stress applied.
What is proportional strength?
When a material deforms, it does so in several stages. The first stage, called the elastic region of deformation, is linear in nature and not permanent. A stress can be applied, and once it's removed, the material will regain all of the deformation. The second stage, plastic deformation, is permanent. A material that has been stressed into the plastic region will regain the elastic deformation, but will permanently maintain the plastic.The proportional strength is the point at which plastic deformation begins.
What happens when force is applied to a metal what property does this demonstrate?
When force is applied to a metal, it deforms and changes shape. This demonstrates the property of ductility, which is the ability of a material to undergo plastic deformation without breaking.
What is meant by modulus strength?
Modulus strength, often referred to as the modulus of elasticity or elastic modulus, is a measure of a material's stiffness or resistance to deformation under stress. It quantifies the relationship between stress (force per unit area) and strain (deformation) in the elastic region of the material's stress-strain curve. A higher modulus strength indicates that a material is stiffer and deforms less when subjected to an applied load. Common types of modulus include Young's modulus, shear modulus, and bulk modulus, each describing different modes of deformation.
Why a stress-strain curve usually has two segments.?
A stress-strain curve typically has two segments because the material first deforms elastically before transitioning to plastic deformation. The initial linear region represents elastic deformation, where the material can return to its original shape after the stress is removed. The second region shows plastic deformation, where the material undergoes permanent deformation due to interatomic sliding or dislocation motion.
How do you calculate stiffness of a elastic material?
When a load is applied to a material it deforms. Elasticity is defined as the ability of a material to return completely to its original state after a load is removed. For example, the reason an elastic band is elastic is that it will return to its original dimensions after being stretched and released. Modulus of elasticity is the measure of this ability and is experimentally determined by measuring how much a material deforms when a given load is applied. A high modulus material is very stiff. A low modulus material is more "rubbery". Engineering calculation of deflection of a design element use Modulus of Elasticity (aka Lambda) an an input.
Does the land sink with the weight of water when the tide comes in?
The weight of the water in the tidal bulge is sufficiently great that it deforms the seafloor. The Earth deforms as an elastic solid, and the deformation extends thousands of kilometers.
What is the relationship between shear modulus and elastic modulus?
The shear modulus and elastic modulus are related properties that describe a material's response to deformation. The shear modulus specifically measures a material's resistance to shearing forces, while the elastic modulus, also known as Young's modulus, measures a material's resistance to stretching or compression. In general, the shear modulus is related to the elastic modulus through the material's Poisson's ratio, which describes how a material deforms in response to stress.
What is Elastic perfectly plastic?
Elastic perfectly plastic refers to a material behavior model where a material behaves elastically up to a certain yield stress and then undergoes plastic deformation without any increase in stress. In this model, once the yield point is reached, the material deforms permanently, and the stress remains constant regardless of further deformation. This behavior is typically represented in a stress-strain curve, where the initial linear elastic region is followed by a horizontal plastic region. Such materials do not exhibit strain hardening, meaning they do not gain strength with increased deformation.
If a material can permanently deform in all directions what is this called?
This is called isotropic deformation, where the material deforms equally in all directions.
Name the phenomenon that occurs when a etal is loded well witin the elastic range at a temperatue of 800 degrees andit slowly deforms permanently?
The phenomenon you are describing is known as creep. Creep is the slow, time-dependent deformation of a material under a constant load or stress, typically occurring at elevated temperatures. In this case, the material is being loaded within its elastic range but still deforms permanently due to the prolonged exposure to high temperature.
An object that deforms when a force is applied to it and returns to its original form when the force is no longer applied is said to be?
Elasticity is the property of deforming under force and regaining shape when the force is removed.
